Have a 9090db in good shape...mono switch seems to have no effect on stereo/mono playback. Signal from both inputs is played back through both speakers all the time??? Balance control shifts entire input back and forth from left to right. No stereo imaging on FM or CD playback.
FM stereo light does come on, though. I have a schematic but no owners manual. HELP!!!
